Description

Tyre alarm for automotive vehicles

The utility model relates to a kind of vehicle tyre warning device.

At present, the tire pressure of power actuated vehicle is to adopt air-pressure gauge to measure when vehicle stops, the time then can not measure in driving, therefore under steam, happen occasionally because of the too small tire screw of air pressure cuts off, cuts the grave accident that axle, spindle nose fracture etc. cause.

The purpose of this utility model is exactly propose at the deficiency of existing measuring pulley air pressure instrument a kind of in vehicle traveling process, the device that can report to the police when the wheel for motor vehicle air pressure is lower than normal barometric pressure.

The utility model is achieved in that this annunciator is made up of locating plate 2, shell 3, swing spring 4, sealing shroud 6, dry-reed tube 7, magnet 8, wherein locating plate 2 is fixed together with swing spring 4, shell 3 is fixed by screw with locating plate, dry-reed tube 7 is arranged in shell 3 bottoms, magnet 8 is fixing with plastic casing 9 in the spring bottom, and two lines that dry-reed tube 7 is drawn link to each other with terminal screw.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model birds-eye view.

Below in conjunction with accompanying drawing the utility model is illustrated:

The locating plate 2 of this device by screw 1 be fixed on self-propelled vehicle bow plate below, shell 3 is to the tire direction, spring 4 small ends are downward, empty wagons is installed small end and the road surface is not more than 4 centimetres, and when tire pressure was lower than normal value, vehicle body descended in driving, contact to earth in the swing spring lower end simultaneously, moves backward, moves after the inner magnet, during to certain position, causing that electronic original part closes closes, energized, and the hummer in this moment operator's compartment begins to report to the police, get final product parking maintenance, can avoid unnecessary loss.

This device construction is reasonable, simple installation, value of service height.
